Workers wearing protective clothing check the air quality in Gudang, Brazil, Malaysia, June 25, local time. According to foreign media reports, 75 students in Johor, Malaysia, suffered from breathing difficulties and vomiting. More than 400 schools in the state were suspended. According to foreign media reports, the outbreak of the pollution occurred on June 20. Besides students, many local people also suffered from physical discomfort symptoms. Johor State Minister Sarudin announced in the evening of the 24th that as of 3 p.m. on the 24th, a total of 75 students had been sent to the hospital for treatment, four of whom had been transferred from the intensive care unit to the general ward. Students interviewed pointed out that they had smelled pungent odors like gas. More than 100 primary and secondary schools and 300 private kindergartens have been ordered to close temporarily, according to foreign media reports on May 25. On the 25th, Malaysian Prime Minister Mahathir said that the authorities were still trying to identify the causes of pollution and warned that severe measures would be taken.

The Johor State Government preliminarily judged that the source of air pollution in Gudang, Brazil, was not a river, and was discharging 30 suspicious factories in the area. Authorities have set up roadblocks on major roads to inspect suspicious vehicles in order to prevent operators from transporting toxic waste. Mohammed Kuzan, an official in charge of health and cultural heritage at the Johor State Government, said that of the 30 factories inspected by the Johor Environment Agency, one dealt with toxic waste.

He said that the Environmental Bureau had come to the factory to collect waste samples for testing to determine whether it was the source of the pollution incident.

He has instructed the Environmental Bureau, the local government and relevant agencies to act together, and once suspicious factories are found, they will be prosecuted.

It is reported that in March 2019, in the same area of Malaysia, more than 5,000 people were ill because of illegal dumping of toxic waste into rivers. But the authorities said that the rubbish caused by the incident had been cleaned up and had nothing to do with the air pollution incident.
